For example the URL for an account uses the following format: <account_identifier>.snowflakecomputing.com
Example Snowflake account identifier hj1234.eu-central-1.
Redshift and Postgres host_settings are loaded from field host field.
Example Redshift host: redshift-cluster-example.123456789.eu-central-1.redshift.amazonaws.com
